Welcome to LEDs Magazine’s Connected SSL & Controls newsletter for Nov. 13, 2023. The inherent controllability of LED devices is undisputed. However, to achieve reliable operation, lifetime claims, and energy efficiency goals, one must consider the type of controls incorporated with LED systems. This was the goal of a study conducted by a Pacific Northwest National Laboratory (PNNL) team, who continued an investigation into variations in response of commercial LED streetlights to analog 0-10V control signals. The researchers found that a lack of calibration to these signals made a significant difference when combined with several light output and power modulation strategies, affecting the luminaires’ expected energy and cost savings. Still, their findings resulted in recommendations that could improve the performance of these luminaires and control systems, or prescribe alternative configurations.

Also in this issue, the L-Prize Prototype Phase winners achieved marks for advancing interoperability, sustainability, and accessibility of commercial connected lighting, while Recolight has slightly modified its approach to its previously announced lighting reuse portal. Reconditioned luminaires alongside appropriate lighting controls will undoubtedly help companies reach their carbon footprint objectives.
